The long story:

Java uses "$" as the namespace separator for nested (inner) classes. 
Unfortunatly a few platforms (ie AIX) don't allow this character in 
assembler labels. The idea is for the config for such platforms to 
declare NO_DOLLAR_IN_LABEL and the compiler will mangle occurances of 
"$" into something else. Even more unfortunatly C++ ignores this, and 
elfos.h incorrectly defines it, which make it more or less useless. To 
make it do something useful, the C++ and Java front-ends need to agree 
on a common mangling for "$" when the platform does not allow it, and 
elfos.h needs to stop defining it. Or, even better, some generic part of 
the compiler (varasm?) could do the mangling when it sees 
NO_DOLLAR_IN_LABEL.
